If your shares of common stock are held in street name (held for your account by a broker or other nominee):

How do I attend the Annual Meeting online?

We will be hosting our Annual Meeting via live webcast only. Any stockholder can attend the Annual Meeting live online by registering at www.virtualshareholdermeeting.com/MNTS2024. In order to attend the Annual Meeting, you must provide the control number located on your proxy card. Upon completing your registration, you will access to the Annual Meeting and be able to vote and submit questions during the Annual Meeting. The webcast will start at 9:00 a.m. pacific time on June 28, 2024, and you are encouraged to log-in with your control number at least 15 minutes early.

What are the Board of Directors’ recommendations on how to vote my shares?

The Board of Directors recommends a vote:

Proposal 1: FOR election of the two Class II director nominees and the two Class III director nominees (page 6).

Proposal 2: FOR ratification of the selection of Frank, Rimerman + Co. LLP as the Company’s independent registered public accounting firm (page 26).

Proposal 3: FOR the Warrant Repricing Proposal (page 30).

Who pays the cost for soliciting proxies?

The Company will pay the cost for the solicitation of proxies by the Board of Directors. The solicitation of proxies will be made primarily by mail and through internet access to materials. Proxies may also be solicited personally, by telephone, fax or email by employees of the Company without any remuneration to such individuals other than their regular compensation. The Company will also reimburse brokers, banks, custodians, other nominees and fiduciaries for forwarding these materials to their principals to obtain the authorization for the execution of proxies. The Company may also engage a third party proxy solicitor whose services would be paid by the Company.

Will my shares be voted if I do not return my proxy?

If your shares are registered directly in your name, you are a “stockholder of record” who may vote at the Annual Meeting. As the stockholder of record, you have the right to direct the voting of your shares by voting over the internet, by telephone, by returning your proxy or by voting online during the Annual Meeting.

If your shares are held in an account at a bank or at a brokerage firm or other nominee holder, you are considered the beneficial owner of shares held in “street name,” and these proxy materials are being forwarded to you by your bank, broker or other nominee who is considered the stockholder of record for purposes of voting at the Annual Meeting. As the beneficial owner, you have the right to direct your bank, broker or other nominee on how to vote your shares and to participate in the Annual Meeting. You will receive instructions from your bank, broker or other nominee explaining how you can vote your shares and whether they permit internet or telephone voting. Follow the instructions from your bank, broker or other nominee included with these proxy materials, or contact your bank, broker or other nominee to request a voting instruction form. We encourage you to provide voting instructions to your bank, broker or other nominee by giving your voting instruction to them. This ensures that your shares will be voted at the Annual Meeting according to your instructions. If you want to vote in person virtually at the Annual Meeting, you must obtain a legal proxy from your broker, bank or other nominee and to submit a copy to the Company’s Corporate Secretary in advance of the meeting. Further instructions will be provided to you as part of your registration process.

Note that under New York Stock Exchange, or NYSE, rules that apply to voting by nominees, which apply to both NYSE- and Nasdaq-listed companies, if you hold shares through a bank, broker or other institution and you do not provide your voting instructions to them at least 10 days before the Annual Meeting, that firm has the discretion to vote your shares on proposals that NYSE has determined are routine. Such firm will not have the discretion to vote your shares on proposals that NYSE has determined are non-routine. For purposes of the proposals in this proxy statement, the election of director nominees is a non-routine matter, and the appointment of an independent registered public accounting firm is a routine matter. A “broker non-vote” refers to a share represented at the meeting held by a broker, as to which instructions have not been received from the beneficial owner or person entitled to vote such shares and with respect to which, on one or more but not all matters, the broker does not have discretionary voting power to vote such share.

Can I change my vote?

You may revoke your proxy at any time before it is voted by notifying the Company’s Corporate Secretary in writing, by returning a signed proxy with a later date, by transmitting a subsequent vote over the internet or by telephone prior to the close of the internet voting facility or the telephone voting facility. You may also attend the virtual meeting and vote during the meeting. If your stock is held in street name, you must contact your broker or nominee for instructions as to how to change your vote.

How is a quorum reached?

The presence, by virtual attendance or by proxy, of holders of at least a one-third of the total number of outstanding shares entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting. Shares held of record by stockholders or brokers, bankers or other nominees who do not return a signed and dated proxy or attend the Annual Meeting virtually will not be considered present or represented at the Annual Meeting and will not be counted in determining the presence of a quorum. Abstentions and broker non-votes, if any, will be counted for purposes of determining whether a quorum is present for the transaction of business at the Annual Meeting.

What vote is required to approve each item and how are votes counted?

Votes cast by proxy or online at the Annual Meeting will be counted by the persons appointed by the Company to act as tabulators for the Annual Meeting. The tabulators will count all votes FOR, AGAINST, abstentions and broker non-votes, as applicable, for each matter to be voted on at the Annual Meeting. Abstentions and broker non-votes are not counted as votes cast and, therefore, do not have the effect of votes in opposition to the proposals described in this Proxy Statement. A broker non-vote occurs when a

nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.

Proposal 1—Election of two Class II and two Class III director nominees

The four nominees for director to receive the highest number of votes FOR election will be elected as directors. This is called a plurality. Proposal 1 is a non-routine matter. Therefore, if your shares are held by your brokerage firm in street name and you do not timely provide voting instructions with respect to your shares, your brokerage firm cannot vote your shares on Proposal 1. Shares held in street name by banks, brokerage firms or other nominees who indicate on their proxies that they do not have authority to vote the shares on Proposal 1 will not be counted as votes FOR or WITHHELD from any nominee. As a result, such “broker non-votes” will have no effect on the voting on Proposal 1. You may:

Votes that are withheld will not be included in the vote tally for the election of the director.

Proposal 2—Ratification of the selection of Frank, Rimerman + Co. LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024

To approve Proposal 2, holders of a majority of the votes cast on the matter must vote FOR the proposal. For the ratification of the selection of Frank, Rimerman + Co. LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024, the votes cast FOR must exceed the votes cast AGAINST. Only FOR and AGAINST votes will affect the outcome. Abstentions will have no effect on the voting of Proposal 2. Proposal 2 is a routine matter. Therefore, if your shares are held by your bank, broker or other nominee in street name and you do not vote your shares, your bank, broker or other nominee may vote your shares on Proposal 2.

Proposal 3—The Warrant Repricing Proposal

To approve Proposal 3, holders of a majority of the votes cast on the matter must vote FOR the proposal. For the approval of the Warrant Repricing Proposal, the votes cast FOR must exceed the votes cast AGAINST. Only FOR and AGAINST votes will affect the outcome. Abstentions will have no effect on the voting of Proposal 3. We believe that the Warrant Repricing Proposal involves matters that we believe will be considered non-routine and brokers and other intermediaries will not have the discretion to vote in it without voting instructions. We encourage you to provide voting instructions to the organization that holds your shares by carefully following the instructions provided by such organization.

If there are insufficient votes to approve Proposals 1, 2, or 3, your proxy may be voted by the persons named in the proxy to adjourn the Annual Meeting in order to solicit additional proxies in favor of the approval of such proposal. If the Annual Meeting is adjourned or postponed for any purpose, at any subsequent reconvening of the Annual Meeting, your proxy will be voted in the same manner as it would have been voted at the original convening of the Annual Meeting unless you withdraw or revoke your proxy. Your proxy may be voted in this manner even though it may have been voted on the same or any other matter at a previous session of the Annual Meeting.

Could other matters be decided at the Annual Meeting?

The Company does not know of any other matters that may be presented for action at the Annual Meeting. Should any other business come before the Annual Meeting, the persons named on the enclosed proxy will have discretionary authority to vote the shares represented by such proxies in accordance with their best judgment. If you hold shares through a broker, bank or other nominee as described above, they will not be able to vote your shares on any other business that comes before the Annual Meeting unless they receive instructions from you with respect to such matter.

What happens if the meeting is postponed or adjourned?

Your proxy may be voted at the postponed or adjourned Annual Meeting. You will still be able to change your proxy until it is voted.

How can I find out the results of the voting at the Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting. Final voting results will be published in a Current Report on Form 8-K, or Form 8-K, that we expect to file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

What does it mean if I receive more than one proxy card or voting instruction form?

It means that you have multiple accounts at the transfer agent or with brokers. Please complete and return all proxy cards or voting instruction forms to ensure that all of your shares are voted.

What if I have technical difficulties or trouble accessing the Annual Meeting?

If you encounter any technical difficulties with the virtual meeting platform on the Annual Meeting day, please call the technical support number that will be posted on the virtual Annual Meeting log-in page. Technical support will be available starting at 8:45 a.m. pacific time on June 28, 2024 and will remain available until the Annual Meeting has ended.

What are the implications of being an “emerging growth company” and “smaller reporting company”?

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding nonbinding advisory votes on executive compensation and stockholder approval of any golden parachute payments not previously approved. We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year (a) in which we are deemed to be a “large accelerated filer” under the Securities Exchange Act of 1934, as amended, or the Exchange Act, (b) in which we have total annual gross revenue of at least $1.235 billion, or (c) following the fifth anniversary of the closing of our initial public offering; or (ii) the date on which we have issued more than $1 billion in non-convertible debt in the prior three-year period.

We are also a “smaller reporting company,” meaning that the market value of our stock held by non-affiliates is less than $700 million and our annual revenue was less than $100 million during the most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies.

Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

Who should I contact if I have any additional questions?

If you hold your shares directly, please contract an investor relations representative at investors@momentus.space. If your shares are held in street name, please contact the telephone number provided on your voting instruction form or contact your broker or nominee holder directly.

Proposal 1 - Election of Directors

The Board of Directors has nominated the following individuals for election as Class II directors of the Company’s Board of Directors to serve until the 2026 Annual Meeting and until his successor is elected and qualified or until the individual’s earlier of death, resignation, or removal:

Chris Hadfield

John C. Rood

Additionally, the Board of Directors has nominated the following individuals for election as Class III directors of the Company’s Board of Directors to serve until the 2027 Annual Meeting and until his or her successor is elected and qualified or until the individual’s earlier of death, resignation, or removal:

Linda J. Reiners

Victorino G. Mercado

Each of the above individuals is currently serving as a director of the Company. Biographical information for each nominee is contained in the “Board of Directors and Corporate Governance” section below.

Because the Company was unable to hold its Annual Meeting of Stockholders in 2023, this year’s Annual Meeting will include the election of the two Class II directors of the Company’s Board of Directors and the two Class III directors of the Company’s Board of Directors.

The Board of Directors has no reason to believe that any of its nominees will be unable or unwilling to serve if elected. If a director nominee becomes unable or unwilling to accept nomination or election, either the number of the Company’s directors will be reduced or the persons acting under the proxy will vote for the election of a substitute director nominee that the Board of Directors recommends.

Vote Required

The election of directors in this Proposal 1 requires the affirmative vote of a plurality of the votes validly cast at the election. Neither abstentions nor broker non-votes will have any effect on the outcome of voting on director elections.

Recommendation

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR

THE ELECTION OF EACH OF THE DIRECTOR NOMINEES.

BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Board of Directors

The primary responsibilities of the Board of Directors are to provide oversight, strategic guidance, counseling and direction to the Company’s management. When considering whether directors and director nominees have the experience, qualifications, attributes and skills, taken as a whole, to enable the board to satisfy its oversight responsibilities effectively in light of its business and structure, the board will focus primarily on each person’s background and experience as reflected in the information discussed in each of the directors’ individual biographies set forth below in order to provide an appropriate mix of experience and skills relevant to the size and nature of its business. The board is divided into three classes, with members of each class serving staggered three-year terms. The board held 22 meetings in the 2023 fiscal year, and all directors attended at least 75% of the board meetings.

The following table sets forth information with respect to our current directors:

* = Chairperson

• = Member

At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following their election and until their successors are duly elected and qualified. Directors may be removed for cause by the affirmative vote of the holders of at least two-thirds of the Company’s voting stock.

Because the Company was unable to hold its Annual Meeting of Stockholders in 2023, this year’s Annual Meeting will include the election of the two Class II directors of the Company’s Board of Directors and the two Class III directors of the Company’s Board of Directors.

Corporate Governance

Director Composition

As illustrated by the director biographies on the previous pages, our board is made up of a diverse group of leaders with substantial experience in their respective fields. We believe that diversity in our board’s composition, skills, qualifications and experiences contributes to an effective and well-functioning board. As such, we believe that the board possesses the necessary qualifications to provide effective oversight and insightful strategic guidance for the Company.

We regularly review our board’s composition to identify the skills needed for our Company both in the near term and into the future. We highly value diversity in composition, experience and skills in evaluating and recommending new directors for our board. Ongoing strategic board succession planning assures that the board continues to maintain an appropriate mix of objectivity, skills and experiences to provide fresh perspectives and effective oversight and guidance to management, while leveraging the institutional knowledge and historical perspective of more experienced directors.

Director Independence

Each of the directors on the Board of Directors, other than John C. Rood, qualifies as an independent director, as defined under Nasdaq listing rules, and the board consists of a majority of “independent directors,” as defined under the rules of the SEC and Nasdaq listing rules relating to director independence requirements. In addition, we are subject to the rules of the SEC and Nasdaq relating to the membership, qualifications and operations of the Audit Committee, as discussed below.

Stock Ownership Guidelines

The Board of Directors believes that it is in the best interests of the Company and its shareholders that directors and executive officers have a meaningful proprietary stake in the Company so that their interests are aligned with the interests of shareholders. Accordingly, the board has adopted Stock Ownership Guidelines applicable to our non-employee directors and our executive officers. Our Stock Ownership Guidelines are administered by the Compensation Committee.

Under our Stock Ownership Guidelines, nonemployee directors, the Chief Executive Officer and all other executive officers of the Company are expected to hold stock in accordance with the below table.

Under our Stock Ownership Guidelines, each director and officer is required to achieve the applicable stock ownership level within five years of first becoming subject to the Stock Ownership Guidelines. If an individual becomes subject to a greater ownership amount due to promotion or an increase in base salary, such individual is expected to meet the higher ownership amount within the later of the original period or three years from the effective date of such promotion or increase in base salary.

Hedging Prohibitions

Our Insider Trading Policy prohibits our directors, officers, employees or designated contractors from purchasing any financial instruments, including variable forward contracts, equity swaps, collars or exchange funds, or otherwise engaging in any transactions that hedge or offset any decrease in the market value of the Company’s securities.

Communications with the Board

Any matter intended for the board, or for any individual member of the board, should be directed to Momentus Inc., 3901 N. First Street, San Jose, California 95134, Attention: Corporate Secretary, with a

request to forward the communication to the intended recipient. In general, any stockholder communication delivered to the Company for forwarding to board members will be forwarded in accordance with the stockholder’s instructions. The Company reserves the right not to forward to board members any abusive, threatening or otherwise inappropriate materials.

The board has determined that it should maintain the flexibility to select the Chair of the Board of Directors of the Company and adjust its board leadership structure based on circumstances existing from time to time and based on criteria that are in the Company’s best interests and the best interests of our stockholders, including the composition, skills, diversity and experience of the board and its members, specific challenges faced by the Company or the industry in which we operate and governance efficiency. The board has adopted Corporate Governance Guidelines, which provides for the appointment of a lead independent director at any time when the Chairperson is not independent. As Mr. Rood, our Chief Executive Officer, is the Chairperson of the board, the board has appointed Linda J. Reiners as lead independent director.

Security Director

Under our National Security Agreement (the “NSA”), which terminated effective January 29, 2024, the board includes a director who is approved by the CFIUS Monitoring Agencies. When the NSA was in effect, this director, referred to as the “Security Director,” had a fiduciary duty, to the extent consistent with his or her fiduciary duties to the Company and its stockholders under Delaware law, to the U.S. government. The Security Director served as the primary liaison between the Board of Directors and the CFIUS Monitoring Agencies and had authority to oversee compliance with the NSA. To the extent that the Security Director believed that a conflict of interest was reasonably likely to exist between her or his fiduciary duties under Delaware law to the Company and/or its stockholders and to the CFIUS Monitoring Agencies, the Security Director was required to promptly inform the CFIUS Monitoring Agencies of such conflict. The Security Director is the sole member of the Security Committee of the Board of Directors.

In addition to the responsibilities above, the Security Director has the following responsibilities under the NSA:

Our second amended and restated certificate of incorporation provides that the Security Director may only be removed for cause and with the approval of the CFIUS Monitoring Agencies and at least two-thirds of the voting power of the then outstanding shares of capital stock of the Company entitled to vote generally in the election of directors voting as a single class.

Board Role in Risk Oversight

One of the key functions of the board is informed oversight of the Company’s risk management process. This oversight function is administered directly through the board as a whole, as well as through various standing committees of the board that address risks inherent in their respective areas of oversight. In particular, the board is responsible for monitoring and assessing strategic risk exposure and the Company’s Audit Committee has the responsibility to consider and discuss the Company’s major financial risk exposures and the steps its management will take to monitor and control such exposures, including guidelines and

policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements. The Compensation Committee assesses and monitors whether the Company’s compensation plans, policies and programs comply with applicable legal and regulatory requirements. The Nominating and Corporate Governance Committee monitors the effectiveness of Company’s governance guidelines.

Committees of the Board of Directors

The Company has an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee, each of which has the composition and responsibilities described below. Members serve on these committees until their resignation or until otherwise determined by the Board of Directors. Each committee operates under a charter approved by the board. Copies of each charter are posted on the Investor Relations section of our website at https://momentus.space. In addition to these committees, the Board has a Security Committee and a Disclosure Committee as described below.

Audit Committee

The members of the Audit Committee are Linda J. Reiners, Kimberly A. Reed and Mitchel B. Kugler. Ms. Reiners is the Chair of the committee. Each member meets the requirements for independence and financial literacy under the current Nasdaq listing standards and SEC rules and regulations, including Rule 10A-3. Ms. Reiners qualifies as an “audit committee financial expert” within the meaning of Item 407(d) of Regulation S-K promulgated under the Securities Act of 1933, as amended (the “Securities Act”). This designation does not impose any duties, obligations, or liabilities that are greater than are generally imposed on members of the Audit Committee and the board.

The Audit Committee is responsible for, among other things:

Compensation Committee

The members of the Compensation Committee are Brian Kabot, Chris Hadfield and Mitchel B. Kugler. Mr. Kabot is the Chair of the committee. Each member meets the requirements for independence under the current Nasdaq listing standards and SEC rules and regulations. Each member of the committee is a non-employee director, as defined in Rule 16b-3 promulgated under the Exchange Act.

The Compensation Committee is responsible for, among other things:

The Compensation Committee’s charter provides that it may delegate authority to one or more subcommittees or one or more officers of the Company. If the Compensation Committee delegates authority to an officer of the Company, such officer will not be delegated any authority that relates to the amount or form of compensation of “officers” as defined in Section 16 of the Exchange Act, which includes the authority related to the administration of compensation and incentive plans and benefit programs.

The charter also provides that the Compensation Committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, legal counsel or other adviser to assist in the evaluation of CEO or executive officer compensation at the Company’s expense, and is directly responsible for the appointment, compensation and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the Compensation Committee will consider the independence of each such adviser, including the factors required by Nasdaq and the SEC.

During the fiscal year ended 2023, the Compensation Committee directly engaged Frederic W. Cook & Co., Inc. (“F.W. Cook”) as a compensation consultant to provide advice and recommendations on the amount and form of executive and non-employee director compensation. F.W. Cook did not provide additional services to the Company in excess of $120,000.

Nominating and Corporate Governance Committee

The members of the Nominating and Corporate Governance Committee are Victorino G. Mercado, Chris Hadfield and Kimberly A. Reed. Mr. Mercado is the Chair of the committee. Each member meets the requirements for independence under the current Nasdaq listing standards and SEC rules and regulations.

The Nominating and Corporate Governance Committee is responsible for, among other things:

As set out in its charter, the Nominating and Corporate Governance Committee is responsible for the consideration of stockholder-proposed director nominees for election to the board. The Company’s amended and restated bylaws, as amended, specifically provides the procedures to be followed by stockholders submitting such recommendations. For more information regarding the process and procedures stockholders are required to follow in submitting director nominees, see “Stockholder Proposals and Director Nominations other than Pursuant to Rule 14a-8” on page 32.

Security Committee

The board has a Security Committee comprised of the Security Director. The Security Committee is responsible for overseeing and monitoring Momentus’ operations to ensure that the protective measures contained in the recently terminated NSA are effectively maintained and implemented; and overseeing the

development and implementation of policies and procedures to safeguard protected technical information, protected systems and protected facilities in accordance with export control regulations. For more information about the Security Committee, see above under “Corporate Governance – Security Director” on page 12.

Disclosure Committee

The members of the Disclosure Committee are Mitchel B. Kugler, Chris Hadfield, and John C. Rood. Mr. Kugler is the Chair of the committee.

The Disclosure Committee is overseen by the Audit Committee and is responsible for, among other things:

Compensation Committee Interlocks and Insider Participation

None of the members of the Compensation Committee is or has been at any time one of Momentus’ officers or employees. None of Momentus’ executive officers currently serves, or in the past fiscal year has served, as a member of the board of directors or compensation committee (or other Board of Directors committee performing equivalent functions or, in the absence of any such committee, the entire Board of Directors) of any entity that has one or more executive officers serving as a member of Momentus’ board or Compensation Committee.

Code of Business Conduct

The Board of Directors has adopted a Code of Business Conduct that applies to all of our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. The Code of Business Conduct is available in the Corporate Governance section of the Investor Relations page on our website at www.momentus.space. In addition, we have posted on the Corporate Governance section of our website all disclosures that are required by law or Nasdaq listing standards, including any amendments to, or waivers from, any provision of the Code of Business Conduct.

EXECUTIVE COMPENSATION

The Company qualifies as a “smaller reporting company” under rules adopted by the SEC. Accordingly, the Company has provided scaled executive compensation disclosure that satisfies the requirements applicable to the Company in its status as a smaller reporting company. Under the scaled disclosure obligations, the Company is not required to provide, among other things, a compensation discussion and analysis or a compensation committee report, and certain other tabular and narrative disclosures relating to executive compensation.

Our named executive officers (or “NEOs”) for 2023 were as follows:

John C. Rood, our Chief Executive Officer, President and Chair of the Board;

Paul Ney, our Chief Legal Officer and Corporate Secretary; and

Rob Schwarz, our Chief Technology Officer.

Certain information regarding the compensation of our NEOs for 2023 is provided on the following pages.

Summary Compensation Table

The Summary Compensation Table below summarizes the compensation paid to, awarded to, or earned by our Chief Executive Officer and our two other most highly compensated officers for the 2023 fiscal year. The footnotes to the Summary Compensation Table set forth narrative discussions of the material factors necessary to understand the information disclosed in the table.

Narrative to the Summary Compensation Table

The following is a discussion of certain terms of the employment agreements with our NEOs that we believe are necessary to understand the information disclosed in the Summary Compensation Table.

Base Salaries

The Company’s NEOs receive a base salary for services rendered to the Company. The base salary payable to each NEO is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities.

Bonuses

In fiscal year 2023, Mr. Rood, Mr. Ney, and Mr. Schwarz were eligible to earn annual cash bonuses targeted at 100%, 50%, and 30%, respectively, of their respective base salaries based on their performance, as determined by the Momentus Board of Directors.

Equity Compensation

Our Compensation Committee administers our 2021 Equity Incentive Plan (the “Equity Incentive Plan”) and approves the amount of, and terms applicable to, grants of stock options, RSUs, and other types of equity awards to employees, including the Named Executive Officers.

The Equity Incentive Plan is intended to (i) attract and retain the best available personnel to ensure our success and accomplish our goals; (ii) incentivize employees, directors and independent contractors with long-term equity-based compensation to align their interests with our stockholders; and (iii) promote the success of our business.

The Equity Incentive Plan permits the grant of incentive stock options, nonstatutory stock options, stock appreciation rights (“SARs”), restricted stock, RSUs and stock bonus awards (all such types of awards, collectively, “equity awards”), although incentive stock options may only be granted to employees.

For the grant date fair values of the options and RSUs, please see the Summary Compensation Table above.

Perquisites

In 2023, Momentus provided its NEOs with benefits intended to be competitive with market practices and to motivate them to carry out their duties with respect to the Company. Some of these benefits are provided under the NEOs’ applicable employment agreements, as described below. The amount of these benefits has been included in the Summary Compensation Table in the “All Other Compensation” column.

Momentus pays the entire premiums associated with its NEOs’ medical insurance coverage; because the Company does not pay the entire premium with respect to the medical insurance coverage of employees generally, the amounts associated with the additional percentage paid by the Company have been included in the Summary Compensation Table in the “All Other Compensation” column.

The Company has established a 401(k) plan which covers all employees. Participants may make voluntary contributions to the plan subject to Internal Revenue Service limitations. The Company does not provide a matching contribution. Momentus also provides other benefits to its NEOs on the same basis as provided to all of its employees, including vacation and paid holidays.

Rood Employment Agreement

Under the Rood Employment Agreement, if Mr. Rood’s employment is terminated by Momentus without “cause” or by Mr. Rood for “good reason” (as such terms are defined in the Rood Employment Agreement) and Mr. Rood executes a release of claims, Mr. Rood will be entitled to (i) the aggregate amount of his base salary and target annual bonus, payable over a 12-month period from the date of his termination; (ii) a lump sum cash payment equal to his prorated annual bonus for the fiscal year during which Mr. Rood is terminated, based on actual performance; (iii) reimbursements equal to the portion of the monthly health premiums paid by Momentus on his behalf and that of his eligible dependents immediately preceding the date that his employment terminates until the earlier of (a) 12 months following the date of termination and (b) the date that Mr. Rood and his eligible dependents become ineligible for COBRA coverage; and (iv) his outstanding unvested equity awards will vest as to that number of shares or units that would have vested had Mr. Rood remained employed until the 12-month anniversary of his termination date.

In addition, the Rood Employment Agreement provides that if Mr. Rood’s employment is so terminated in the period beginning three months prior to and ending 24 months following a “change in control” (as defined in the Rood Employment Agreement) and Mr. Rood executes a release of claims, he will be entitled to receive (i) a lump sum payment in the aggregate amount of 18 months of his base salary plus one and one-half times his target annual bonus, (ii) a lump sum cash payment equal to 150% of his prorated annual bonus for the fiscal year during which Mr. Rood is terminated based on actual performance, (iii) reimbursements equal to the portion of the monthly health premiums paid by Momentus on his and his eligible dependents’ behalf immediately preceding the date that his employment terminates until the earlier of (a) 18 months following the date of termination and (b) that date that Mr. Rood and his eligible dependents become ineligible for COBRA coverage, and (iv) his outstanding unvested equity awards subject to time vesting will vest in full; provided, that, if Mr. Rood remains employed through the consummation of the change in control and the successor to the Company or any affiliate of such successor does not agree to assume, substitute or otherwise continue such equity awards at the time of the change in control, his equity awards will vest in full immediately prior to, and contingent upon, the consummation of such change in control.

The aforementioned payments will be payable over a period of 6 months from termination. Further, Mr. Ney’s 2021 equity award of RSUs, to the extent then outstanding and unvested, shall vest in full. A Change in Control (as defined in the Ney Employment Agreement), will also trigger full vesting of Mr. Ney’s equity award.

Outstanding Equity Awards at Fiscal-Year End

The following table provides information about the number of outstanding equity awards held by our NEOs on December 31, 2023.

DIRECTOR COMPENSATION

Director Compensation Policy

The Company adopted a non-employee director compensation policy to govern the Board of Directors. The policy is designed to attract and retain high quality non-employee directors by providing competitive compensation and align their interests with the interests of stockholders through equity awards. It will cover the compensation of all roles on the Board of Directors other than the Security Director and the Chairperson of the Security Committee.

Specifically, the policy provides for the following annual cash retainers, which will be payable quarterly in arrears and pro-rated for partial quarters of service:

Annual Board Member Service Retainer

Annual Committee Member Service Retainer

Annual Committee Chair Service Retainer (in lieu of Annual Committee Member Service Retainer)

Equity Compensation

Non-employee directors will receive annual RSU grants under the Equity Incentive Plan on the date of the Company’s Annual Meeting of Stockholders which will vest, subject to continuous service through the applicable vesting date:

Accelerated Vesting

The vesting of the RSU grants will accelerate in full if the non-employee director remains in continuous service until immediately prior to such director’s: (i) death, (ii) “disability,” or (iii) the closing of a “change in control” transaction (as “disability” and “change in control” are defined in the Equity Incentive Plan).

Other Terms

To avoid adverse tax consequences to non-employee directors who reside outside of the United States, the board, in its sole discretion, may provide for non-statutory stock options of equal value in lieu of RSU grants, which will have a term of ten years from the date of grant and an exercise price per share equal to 100% of the fair market value of the underlying Class A common stock on the date of grant. All other terms and conditions that apply to RSU grants under the non-employee director compensation policy will apply to such options.

If permitted by the Company, a non-employee director may elect to defer cash retainers and/or RSU awards prior to being earned into deferred stock units of the Company, which shall settle upon the earlier to occur of the director’s “separation from service” as defined in the Treasury Regulations under Section 409A of the Internal Revenue Code of 1986, as amended, or the date determined by the Company.

The Company will reimburse each non-employee director for ordinary, necessary and reasonable out-of-pocket travel expenses to cover in-person attendance at, and participation in, Board of Directors and committee meetings, provided they are reimbursed in accordance with the Company’s travel and expense policy.

Security Director and Chairperson of Security Committee

In addition to compensation under the non-employee director compensation policy, Victorino G. Mercado, as the Security Director and the Chairperson of the Security Committee, will receive additional compensation pursuant to the terms of his offer letter. Mr. Mercado will receive an annual cash retainer of $50,000, payable quarterly in arrears and pro-rated for partial quarters of service.

Compensation of Directors

The following table provides information about the compensation of directors for the fiscal year ended December 31, 2023. John C. Rood is compensated outside of the director compensation framework, as specified further in “Executive Compensation – Summary Compensation Table.”

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

Security Ownership of Certain Beneficial Owners

The following table sets forth certain information known to us regarding the beneficial ownership of our Class A common stock as of May 9, 2024 for each of our NEOs, executive officers, directors, all executive officers and directors as a group and each person known by us to be the beneficial owner of more than 5% of our Class A common stock. Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she, or it possesses sole or shared voting or investment power over that security. Under those rules, beneficial ownership includes securities that the individual or entity has the right to acquire, such as through the exercise of warrants or stock options or the vesting of RSUs, within 60 days of May 9, 2024. Class A common stock subject to warrants or options that are currently exercisable or exercisable within 60 days of May 9, 2024 or subject to RSUs that vest within 60 days of May 9, 2024 are considered outstanding and beneficially owned by the person holding such warrants, options or RSUs for the purpose of computing the percentage ownership of that person but are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Except as noted by footnote, and subject to community property laws where applicable, based on the information provided to us, we believe that the persons and entities named in the table below have sole voting and investment power with respect to all shares shown as beneficially owned by them. Unless otherwise noted, the business address of each of our directors and executive officers is c/o Momentus Inc., 3901 N. First Street, San Jose, California 95134. The percentage of beneficial ownership of our shares of Class A common stock is calculated based on 16,625,904 shares of Class A common stock outstanding as of May 9, 2024.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Compensation arrangements with our NEOs and directors are described elsewhere in this proxy statement.

See “Security Ownership of Certain Beneficial Owners and Management” for information regarding the ownership of our securities held by our control persons.

Other than the foregoing, the following is a description of each transaction since January 1, 2023 and each currently proposed transaction in which:

Indemnification Agreements

Our second amended and restated certificate of incorporation, as amended, contains provisions limiting the liability of executive officers and directors, and our amended and restated bylaws, as amended, provide that the Company will indemnify each of its officers and directors to the fullest extent permitted under Delaware law.

We have entered into indemnification agreements with all of our directors and executive officers and certain other key employees. The indemnification agreements provide that the Company will indemnify each of its directors and executive officers against any and all expenses incurred by such director or executive officer because of his or her status as one of the Company’s directors or executive officers to the fullest extent permitted by Delaware law, our second amended and restated certificate of incorporation, as amended, and our amended and restated bylaws, as amended. In addition, the indemnification agreements provide that, to the fullest extent permitted by Delaware law, the Company will advance all expenses incurred by its directors and executive officers in connection with a legal proceeding involving his or her status as a director or executive officer.

Related Party Transactions Policy

Our related party transactions written policy provides that officers, directors, holders of more than 5% of any class of the Company’s voting securities, and any member of the immediate family of, and any entity affiliated with, any of the foregoing persons, will not be permitted to enter into a related-party transaction with the Company without the prior consent of the Audit Committee, or other independent members of the board in the event it is inappropriate for the Audit Committee to review such transaction due to a conflict of interest. Any request for the Company to enter into a transaction with an executive officer, director, principal stockholder, or any of their immediate family members or affiliates, in which the amount involved exceeds $120,000, must first be presented to the Audit Committee for review, consideration and approval. In approving or rejecting the proposed transactions, the Audit Committee will take into account all of the relevant facts and circumstances available.

Proposal 2 – Ratification of Appointment of Independent Registered Public Accounting Firm

The Audit Committee is responsible for the appointment, compensation (including final approval of audit and other fees), retention and oversight of the independent registered public accounting firm that audits our financial statements and our internal control over financial reporting. The Audit Committee has appointed Frank, Rimerman + Co. LLP (“Frank, Rimerman”) as the independent registered public accounting firm to audit our consolidated financial statements for the year ending December 31, 2024, including the audit of our internal control over financial reporting. Representatives of Frank, Rimerman are expected to be present at the Annual Meeting and will be offered the opportunity to make a statement if they so desire. They will also be available to respond to appropriate questions.

The Audit Committee annually reviews Frank, Rimerman’s independence and performance in deciding whether to retain Frank, Rimerman or engage an alternative independent auditor. As part of this review, the Audit Committee, among other factors, considers the following:

In addition to Frank, Rimerman’s conclusion that they are independent, the Audit Committee believes that Frank, Rimerman is independent and that there are controls and processes that help ensure such independence including the following: (a) Audit Committee oversight of Frank, Rimerman includes at least four private meetings each year and an additional four private meetings with the Audit Committee Chair prior to each quarterly Audit Committee meeting; (b) Audit Committee interaction with, and review of, the industry and other qualifications of the lead partner and of the concurring partner including periodic rotation of such partners; (c) oversight of non-audit services that require preapproval by the Audit Committee precludes certain non-audit services and determines that Frank, Rimerman is an appropriate service provider; (d) discussions with Frank, Rimerman regarding their internal system of quality control including the firm’s internal quality reviews and procedures for maintaining independence with regard to audit clients; and (e) the overall regulatory framework and regulations and requirements of the PCAOB and the SEC that Frank, Rimerman is subject to as an independent registered public accounting firm.

We are asking you to ratify the selection of Frank, Rimerman as our independent registered public accounting firm for the 2024 fiscal year. Although ratification is not required by our amended and restated bylaws, as amended, or otherwise, the board is submitting the selection of Frank, Rimerman to our stockholders for ratification because we value your views on our independent registered public accounting firm and as a matter of good corporate practice. In the event that our stockholders fail to ratify the selection, it will be considered as a direction to the Audit Committee to consider the selection of a different firm. Even if the selection is ratified, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of us and our stockholders.

Audit Committee Report

The Audit Committee annually reviews the performance of its duties under its charter. The charter complies with all current regulatory requirements, including requirements pertaining to the Nasdaq listing standards definitions, provisions and applicable exceptions concerning the independence of audit committee members.

In 2023, the Audit Committee held 4 meetings. The Audit Committee’s meeting agendas are established by the Audit Committee Chair, Linda J. Reiners. The Audit Committee met with the senior members of the Company’s financial management team prior to each meeting.

As previously reported on the Company’s Current Report on Form 8-K, dated July 25, 2023, on July 19, 2023, the Company was informed by Armanino LLP (“Armanino”), the Company’s then independent registered public accounting firm, that Armanino would resign as the Company’s independent registered public accounting firm effective as of the filing of the Company’s quarterly report on Form 10-Q for the fiscal quarter ending September 30, 2023 (the “Q3 Form 10-Q”). Armanino advised the Company that its decision to resign was due to Armanino’s transition away from providing financial statement audit services to public companies. In light of Armanino’s determination, the Audit Committee initiated a process to select a new accounting firm to serve as the Company’s independent registered public accountant commencing with the audit of the Company’s financial statements for the fiscal year ended December 31, 2023. The Company filed the Q3 Form 10-Q on November 14, 2023, at which time Armanino’s resignation became effective.

On December 2, 2023, the Audit Committee appointed Frank, Rimerman to serve as the principal accountant to audit the Company’s financial statements.

Armanino audited the Company’s consolidated financial statements as of and for the fiscal years ended December 31, 2022 and 2021. The reports of Armanino on the financial statements of the Company for the fiscal years ended December 31, 2022 and 2021 did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the Company’s fiscal years ended December 31, 2022 and 2021, and through the interim period ended March 31, 2023, there were no disagreements between the Company and Armanino on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Armanino, would have caused Armanino to make reference to the subject matter of the disagreements in connection with its audit reports on the Company’s financial statements. During the Company’s fiscal years ended December 31, 2022 and 2021, and the interim period ended March 31, 2023, Armanino did not advise the Company of any “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K with respect to the Company.

During the fiscal years ended December 31, 2021 and 2022, and the subsequent interim period through September 30, 2023, the Company has not consulted with Frank, Rimerman regarding either: (i) the application of accounting principles to any specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements; or (ii) any matter that was either the subject of a disagreement (as defined in Regulation S-K, Item 304(a)(1)(iv) and the related instructions) or reportable event (as defined in Regulation S-K, Item 304(a)(1)(v)).

The Audit Committee appointed Frank, Rimerman as the Company’s independent registered public accounting firm for the year ended December 31, 2023, and reviewed with the Company’s financial managers, the independent registered public accounting firm, and the Company’s internal auditor, overall audit scopes and plans, the results of internal and external controls and the quality of the Company’s financial reporting.

The Company’s management is primarily responsible for the preparation, presentation and integrity of the Company’s financial statements, accounting and financial reporting principles, internal controls, and procedures designed to ensure compliance with accounting standards, applicable laws and regulations. As the Company’s independent registered public accounting firm, Frank, Rimerman is responsible for performing an independent audit of the Company’s consolidated financial statements in accordance with generally accepted accounting principles and for expressing an opinion on the conformity of the audited financial statements to accounting principles generally accepted in the United States of America.

The Audit Committee has reviewed and discussed with management the Company’s audited financial statements as of and for the year ended December 31, 2023. The Audit Committee has also discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the PCAOB and the SEC.

The Audit Committee has received and reviewed the written disclosures and the letter from the independent registered public accounting firm required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence from the Company and its management, and the Audit Committee has discussed with the independent registered public accounting firm such independence. The Audit Committee has also considered whether the independent registered public accounting firm’s provision of non-audit services to the Company is compatible with the auditor’s independence.

Based on the Audit Committee’s reviews and discussions referred to above, the Audit Committee recommended to the board that the audited consolidated financial statements referred to above be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 to be filed with the SEC.

The Audit Committee is comprised of the following members: Linda J. Reiners, Kimberly A. Reed, and Mitchel B. Kugler.

Proposal 3 - Warrant Repricing Proposal

General

Momentus is asking stockholders to approve, in accordance with Nasdaq Listing Rule 5635(d), the repricing of certain existing warrants of the Company (the “Warrant Repricing Proposal”). As previously disclosed, on March 7, 2024, we closed a transaction with an institutional investor as the purchaser (the “Investor”) in which we sold, and the Investor purchased, in a registered direct offering (i) an aggregate of 1,320,000 shares of the Company’s Class A common stock, at a purchase price of $0.865 per share of Class A common stock and one March 2024 Warrant (as defined below), (ii) in lieu of Class A common stock, at the election of the Investor, pre-funded warrants to purchase 3,304,280 shares of Class A common stock, at a purchase price of $0.86499 per pre-funded warrant, and (iii) warrants to purchase 4,624,280 shares of Class A common stock (the “March 2024 Warrants”), pursuant to the terms of a Securities Purchase Agreement (the “Securities Purchase Agreement”) that we entered into with the Investor.

Additionally, the Securities Purchase Agreement provides for a warrant repricing transaction (the “Warrant Repricing Transaction”) with respect to warrants to purchase up to 3,687,000 shares of the Company’s Class A common stock initially issued by the Company to the Investor on January 17, 2024 (the “January 2024 Warrants”). The Securities Purchase Agreement requires the Company, among its other obligations, to hold a meeting of stockholders by June 5, 2024 to request stockholder approval of the Warrant Repricing Transaction (the “Stockholder Approval”) for a reduction of the exercise price from $0.96 per share to $0.74 per share and an extension of the termination date of the January 2024 Warrants to five years following the date on which the Company receives the Stockholder Approval.

If the Stockholder Approval is not obtained at the Annual Meeting, then the Company will be required to call another meeting of stockholders every sixty days thereafter to seek the Stockholder Approval until the earlier of the date Stockholder Approval is achieved and July 17, 2024, which is the date that is six months after the January 17 2024 issuance date of the January 2024 Warrants. If Stockholder Approval is not obtained by July 17, 2024, then automatically and without any approval of stockholders (i) the exercise price of the January 2024 Warrants will be reduced (if and only if such new exercise price on the repricing date is lower than the exercise price of the January 2024 Warrants then in effect) to be the Minimum Price (as defined below) of the Class A Stock on July 17, 2024, and (ii) the termination date of the January 2024 Warrants will be extended to January 17, 2029.

The January 2024 Warrants and the March 2024 Warrants both provide that the Investor will not have the right to exercise any portion of such warrants if the exercise would cause (i) the aggregate number of shares of our Class A common stock beneficially owned by the Investor (together with its affiliates) to exceed 4.99% (or, at the election of the Investor, 9.99%) of the number of shares of Class A common stock outstanding immediately after giving effect to the exercise, or (ii) the combined voting power of the Company’s securities beneficially owned by the Investor (together with its affiliates) to exceed 4.99% (or, at the election of the Investor, 9.99%) of the combined voting power of all of the Company’s securities then outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the warrants.

The Company previously solicited stockholder approval in connection with a similar warrant repricing transaction with respect to warrants to purchase up to 5,808,538 shares of the Company’s Class A common stock initially issued by the Company to the Investor on November 9, 2023 (the “November 2023 Warrants”). The Company called to order a special meeting of stockholders on March 15, 2024 (the “March Special Meeting”) to hold a vote on the repricing transaction of the November 2023 Warrants, however there were not present or represented by proxy a sufficient number of shares of the Company’s common stock in order to constitute a quorum at the March Special Meeting. Due to lack of quorum, the Company later cancelled the adjourned March Special Meeting and therefore, automatically and without any approval of stockholders, (i) the exercise price of the November 2023 Warrants was reduced to be the Minimum Price (as defined below) of the Class A Stock on May 9, 2024, and (ii) the termination date of the November 2023 Warrants was extended to May 9, 2029.

Nasdaq Stockholder Approval Requirement

Listing Rule 5635(d) requires stockholder approval in connection with a transaction, other than a public offering, involving the sale or issuance by the issuer of Common Stock (or securities convertible into or exchangeable for Common Stock) equal to 20% or more of the Common Stock or 20% or more of the voting power of such company outstanding before the issuance for a price that is less than the lower of: (i) the closing price of the Common Stock immediately preceding the signing of the binding agreement for the issuance of such securities and (ii) the average closing price of the Common Stock for the five trading days immediately preceding the signing of the binding agreement for the issuance of such securities (the “Minimum Price” as provided in Nasdaq Listing Rule 5635(d)).

Vote Required

Assuming a quorum is present, the affirmative vote of a majority of the total votes cast on this proposal is required for approval of this Warrant Repricing Proposal. For purposes of the approval of this Warrant Repricing Proposal, abstentions and broker non-votes will have no effect on the result of the vote.

Recommendation

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE WARRANT REPRICING PROPOSAL.
